Hi everyone! I ordered chicks from Murray McMurray and MyPetChicken, both orders set to ship this week. I already called the post office to let them know I have live chicks coming and they said that they will call me to pick them up as soon as they arrive. This is my first time ordering chicks through the mail. Will the hatcheries e-mail me when the chicks ship and include a tracking number? I'm already nervous! Thanks!
